Embodiment 2
[0043] Embodiment 2 prepares hydrophobic insulating coating:
[0044] A. Put the sleeve 1, the outer cylinder 3 and the hanging plate 8 in sequence at room temperature in absolute ethanol and deionized water for ultrasonic cleaning, and place them in an oven to dry after cleaning to obtain the sleeve 1, which has a clean surface. Outer cylinder 3 and hanging plate 8;
[0045] B, 80 parts by weight of nano-SiO 2 and 10 parts by weight of tetraethoxysilane were added to 200 parts by weight of N-methylpyrrolidone solution, heated and stirred at 80°C for 4h, and after naturally cooling to room temperature, the above mixture was filtered and dried to obtain a modified hydrophobic SiO 2 , the modified hydrophobic SiO 2 Mix and stir evenly with 50 parts by weight of dimethylformamide solvent at room temperature to configure a viscous solution, apply the above viscous solution to the surface of sleeve 1, outer cylinder 3 and hanging plate 8, and let it stand at room temperature Cur...
